IgG4-Related Disease: Endocrine Involvement, Clinical Implications, and Management Strategies.

Area of Science:

• Endocrinology
• Rheumatology
• Pathology

Background:

• Immunoglobulin G4-related disease (IgG4-RD) is a systemic fibroinflammatory condition.
• Endocrinological manifestations of IgG4-RD are uncommon and often underdiagnosed.
• Commonly affected endocrine organs include the thyroid and pituitary, presenting as Riedel's thyroiditis, IgG4-related thyroiditis, or hypophysitis.

Purpose of the Study:

• To review the endocrinological manifestations of IgG4-related disease.
• To discuss clinical implications and management strategies for IgG4-RD affecting endocrine organs.
• To emphasize the importance of early diagnosis and multidisciplinary approaches.

Main Methods:

• Literature review focusing on IgG4-related disease and its endocrine manifestations.
• Analysis of diagnostic criteria including serological, radiological, and histopathological findings.
• Overview of current treatment strategies, including corticosteroids and immunosuppressive agents.

Main Results:

• IgG4-RD can affect various organ systems, with endocrine involvement being underrecognized.
• Symptoms result from direct organ infiltration or impaired hormone production.
• Diagnosis relies on a combination of clinical, serological, imaging, and biopsy data.

Conclusions:

• Early identification of IgG4-related disease in endocrine organs is vital.
• Prompt treatment can prevent irreversible glandular damage and hormone deficiencies.
• Increased clinical awareness and collaborative physician efforts are necessary for optimal patient outcomes.
